Yeah I mean HD and HP can go on in the next few years building Type 056 and coast guard vessals which are smaller in tonnage but larger in numbers
24 Type 054A would be a good number or say 22 with two Type 054, all complete by 2015
After building the "critical mass" for the navy both yards can switch to start building the amphibious capability of the navy, HD launched one Type 071 each year in 2010 and 2011 so they can certainly add many LPDs post 2015, let's say they build 6 more LPD and 3 LHD from the period 2015-2020, each amphibious flotilla consisting of 3 LPDs and 1 LHD for each of the 3 fleets
This would mean pretty much since 2006 to 2020 HD and HP would have worked about 15 years building Type 054A FFG, Type 056, coast guard, Type 903 Replenishment tankers, Type 071 and Type 081 LHD
JN keeps up the DDG construction before switching to cruisers or even carriers, either way I think Chinese shipyards will cease construction of "small ticket" items by 2015 and switch to larger combatants, from 2005-2015 would be the years when China added to the backbone the critical mass of the navy, post 2015 we start to see the "big ticket" items , 10,000 ton cruisers, 20,000+ton LPD, 40,000+ton LHD and carriers built on the experience of corvettes, FFG and DDG
